Patent DE-3211640-A1 (DE)
Title: Laterally controlled vanes in the rotor with internal roller tracks
Inventor: BRZOSKA RUDOLF
IPC: F01C21/08
Filed: 1982-03-30
Abstract: The invention is used in a stator-rotor machine. The vanes in the rotor have shafts, which project in the lower part on both sides, with roller bearings, which roll on the inner surface of the roller track and bound the vanes spun out in the rotating rotor such that they move in a circle on the inner wall of the stator, in a sealing manner. The stator-rotor machine with controlled vanes can be used in:   1) vacuum-compressor compression pump: the rotor is installed eccentrically in the stator so that it rotates in a sealing manner in the lower part of the inner surface of the stator. The stator has an induction and an outlet channel in the lower part. Since there is a vacuum behind the vane which is moving in a circle (0 DEG  - lower part of the stator - 180 DEG  -  upper part of the stator) and pressure in front of the vane, the second vane moves out to 180 DEG and the medium is thus sucked in and forced out. It is possible to cool the rotor through the shaft. 2) combustion engine: the inner wall of the stator may have an oval or round shape with surfaces which are rounded at the top and bottom and reach to the rotor in a sealing manner. The stator has an induction and an outlet channel in the lower part. The rotor has compression and combustion vanes. When the rotor rotates from 0 DEG -180 DEG , there is a vacuum behind the vane (induction cycle) and pressure in front of the vane (compression cycle). In consequence, medium is sucked in through the induction channel. The medium is compressed in the combustion chamber in front of the vane (between the compression vane and the combustion vane). After 180 DEG , the combustion vane moves out and takes over the pressure of the burnt medium (the engine torque).   <IMAGE>

Title: Plant container or plant pot
Inventor: SCHOCH CHRISTIAN
IPC: A01G27/04
Filed: 1982-03-31
Abstract: The invention relates to a plant container or plant pot (6) which is arranged inside a jardinière (1) or the like whose wall (3) is impermeable to liquid. This plant container (6) is made of an absorbent material, preferably of clay which has been fired at high temperatures, and has great strength and high porosity so that irrigation water which may be treated with soluble fertilisers is absorbed and stored. Absorbent projections, legs (8) or the like are arranged at the bottom (7) of the container (6) so that a storage space for the further storage of irrigation water is formed between container (6) and jardinière (1). The irrigation water is passed from the container (6) to the root system of the plant, which is embedded in standard potting compost, and the supply is continued via the absorbent action of the legs (8). Such a plant container allows long irrigation intervals, and the plants can remain unattended over a long period. <IMAGE>
Patent DE-3215062-A1 (DE)
Title: Circuit arrangement for testing the processability of memory operands for logical and decimal instructions before instruction execution
Inventor: SALIGER HELMUT
IPC: G06F12/04
Filed: 1982-04-22
Abstract: In a data processing system operating in accordance with the pipeline principle, an instruction editing processor carries out the reading of the instructions, the calculation of the addresses and the reading of operands whilst an instruction execution processor handles the actual execution of instructions and the storing of the results in registers or in the main memory. The instruction editing processor contains a length field test circuit which distinguishes between operands having an operand length of less than or equal to two double words (L </= 15) and operands having an operand length (L > 15) which is more than two double words. This length field test circuit is allocated to an end-of-field test circuit which adds the associated field length (L) to the sum of base and distance address (B1 + D1, B2 + D2) of the first and second operand, with the aid of a carry (C) from the most significant bit position of the distance address part (LOC) within a page (SN), occurring during the logical combination, signals a page transgression of the corresponding operand to the instruction execution processor. <IMAGE>

Title: Reversing switches for stepping switches of transformers
Inventor: SONNTAGBAUER ERNST DIPL ING
IPC: H01H9/00
Filed: 1982-07-02
Abstract: The invention relates to a reversing switch for stepping switches of stepping transformers, having a contact arrangement which consists of one or more moving main contacts that pass the main current, and in which, according to the invention, either one of the stationary main contacts, or one of the moving main contacts, or both are provided with an auxiliary or run-on contact which describes a relative movement with respect to the main contact. As a result of this measure, switching, without restriking, of the small capacitive currents flowing via the reversing contact at the start of the changeover process is ensured with little material and technical complexity.

Patent DE-3341432-A1 (DE)
Title: Playing device
Inventor: VOIGT DIETER
IPC: F16F1/12
Filed: 1983-11-12
Abstract: A playing device or the like is described, having a heavy helical spring as a supporting spring, the ends of which can be attached to parts which are movable relative to each other, for example a seat part and a baseplate. In order to achieve the transition at the ends of the spring from the pitch of the spring to supporting surfaces lying normally to the axis of the spring, connecting plates are firmly but detachably fixed to the ends of the spring, each of them having, on its side facing the helical spring, a bearing region which is designed to ascend at a pitch approximately corresponding to the pitch of the helical spring. On the sides remote from the helical spring, the connecting plates have a supporting surface which lies substantially normally to the axis of the helical spring. This avoids the problem whereby a person using the playing apparatus could be hurt by being trapped in a region of the spring which extends in the manner of a wedge. In comparison with the helical springs which have previously been conventional, which are of flattened design at the ends, the helical spring used in the invention is more economical, since it can be cut to the desired length from a blank and used virtually without any further processing. <IMAGE>

Title: Process for the preparation of a-chloro-N- monomethylacetoacetamide
Inventor: SCHWIENBACHER HELMUT DR
IPC: C07C233/00
Filed: 1984-03-20
Abstract: The application relates to a process for the preparation of a-chloro-N-monomethylacetoacetamide by chlorinating N-monomethylacetoacetamide at a temperature of -10 to -25 DEG C in the presence of urea and freezing-point depressant in an aqueous medium. According to the invention, the process is characterised in that chlorine is passed into the aqueous reaction solution until 60 to 75 mol % of the N-monomethylacetoacetamide are chlorinated, the aqueous phase is then extracted using a chlorine-containing solvent, the resulting organic phase is washed with water, a-chloro-N-monomethylacetoacetamide is obtained from the washed organic phase, and at least part of the aqueous phase is recycled into the chlorination step. The process according to the invention allows a-chloro-N-monomethylacetoacetamide with a purity of at least 98 % to be prepared in a simple manner on an industrial scale.
